 note = {application/pdf, 魚類の摂餌・捕食器官の形態は，その多様な食性に対して様々な適応現象を示している(松原ほか，1965)。歯系や鰓耙，消化管などの摂餌や消化に関係する器官については総括的にまとめられたSuyehiro(1942)の研究がよく知られている。また魚種別あるいは器官別にまとめた研究としては松井(1938)，加福(1952)，Iwai(1956，1964)，山下(1956)，Yasuda(1960)，横田ほか(1961)，Fukusho(1969)，花渕(1973)，Kafuku(1978)，MoK(1977)，鈴木・木村(1978)，駒田(1980，1982)などがある。しかし，これらの中には，歯系や腸型などを解剖学的に調査し，分類形質あるいは系統形質として考察されているものが多く，食性に対する形態的な適応現象を詳細に報告したものほアユ(松井1938)，ポラ(江革1950)，オイカワ属魚類(鈴木・木村197８)などにすぎない。また，魚類の摂餌活動を考える場合に，捕食者の口器の大きさと餌料の大きさとの関係が重要な課題と考えられるが(山田 1978)，これについてはYasuda(1960b)，代田(1970，1978a，b)，矢田(1982)らの研究が知られている程度である。
本研究で扱ったムツの摂餌・消化器官の形態については，すでにSuyehiro(1942)やYasuda(1960b)によって報告されているが，それらはかなり断片的なものである。　
著者らは稚魚から成魚までの各発育段階におけるムツの摂餌・消化器官の形態的特徴を明らかにすると共に，口の大きさと餌料の大きさとの関係や，食性変化に伴うこれらの器官の適応現象について考察した。, The present report deals with the functional morphology of Scombrops boops (Piscec: Perciformes: Scombropidae) in relation to their feeding habits, with particular reference to jaws, stomach, intestine, dentition, gill raker, and size of prey animals.Through the morphometric study of these organs, the authors could successfully make clear significance of the structural adaptions of these organs in relations to the conversion of feeding habits. 
Relative width of lower jaw became larger with body growth. 
Stomach showed ﾄ-shape and did not change morphologically in the specimens larger than 20mm SL. Bind sac of stomach was completed in the specimens ca. 100mm SL. Convolution of intenstine showed N-shape and did not change in the specimens larger than ca. 19mm SL. Relative length of intestine became longer with body growth. Pyloric caeca were completed in the specimens ca. 60mm SL. 
Conical teeth were present on both jaws, vomer, palatines, and pharyngeal bones. Teeth on jaws were larger than those on the other bones. Relative length of the longest teeth on both jaws and relative length and width of vomerine teeth band became larger with body growth in the specimens smaller than 60mm SL,　but they became smaller in the specimens larger than 60mm SL. The posterior portion of palatal teeth were ranged in a single row in all specimens examined here. Their anterior portion also ranged in a single row in the specimens smaller than 20mm SL, but they ranged in two rows in the specimens larger than 70-80mm SL.  
Number of gill rakers ranged from 18 to 25, and did not change in the specimens examined here. Stump-like gill rakers appeared in the specimens larger than 30mm SL, and increased in number with body growth. With body growth, relative length of longest gill raker and relative distance between gill rakers became shorter wider, respectively. 
Area of mouth gape increased with body growth according to the formula log AM=2.034 log SL-1.869 where AM=area of mouth gape in mm and SL=standerd length in mm. Cross-sectional areas of prey animals increased gradually with enlargement of mouth gape of the predator. Maximum size of prey animal was determined primarily by width and depth of prey's body and secondarily by sectional areas of prey.
Considering the results obtained here, it may be deducible that the structures of feeding and digestive organs change ontogenically in relation to the piscivorous behavior of the fish.},
